    Abstract: Methods for the manufacture of the above-mentioned titanium alloy for use in combustion engine exhaust systems are disclosed herein. An exemplary method of the disclosed subject matter for the manufacture of titanium alloy for use in a high temperature and high stress environment includes performing a first heat treatment of the titanium alloy at a first temperature, rolling the titanium alloy to a desired thickness, performing a second heat treatment of the titanium alloy at a second temperature, and performing a third heat treatment of the titanium alloy at a third temperature. In some embodiments, the first temperature is selected such that recrystallization and softening of the titanium alloy is optimized without substantial coarsening of second phase particles and can be approximately 1500-1600° F. In some embodiments, the rolling of the titanium alloy reduces the thickness of the titanium alloy by at least than 65%.

  • Patent number: 8600545
    Abstract: A method for qualifying an automated process for inspecting and sorting particles through the production and use of seed particles is disclosed. In one embodiment, seed particles are produced by forming a conformal surface layer on a plurality of particles, thereby imparting them with at least one property whose value or range of values is the same as or about the same as a value or range of values of a corresponding property of undesirable particles. By introducing a predetermined quantity of seed particles, their detection and removal by the automated sorting system can be used to periodically calibrate and qualify the sorting system without interrupting the manufacturing operations or introducing actual undesirable particles into the process stream. The production and use of seed particles to qualify an automated sorting system is particularly well-suited for use with Ti sponge sorting operations.

  • Patent number: 8551264
    Abstract: A method of manufacturing fine grain titanium alloy sheets that is suitable for superplastic forming (SPF) is disclosed. In one embodiment, a high strength titanium alloy comprising: Al: about 4.5% to about 5.5%, V: about 3.0% to about 5.0%, Mo: about 0.3% to about 1.8%, Fe: about 0.2% to about 0.8%, O: about 0.12% to about 0.25% with balance titanium is forged and hot rolled to sheet bar, which is then fast-cooled from a temperature higher than beta transus. According to this embodiment, the sheet bar is heated between about 1400° F. to about 1550° F. and rolled to intermediate gage. After reheating to a temperature from about 1400° F. to about 1550° F., hot rolling is performed in a direction perpendicular to the previous rolling direction to minimize anisotropy of mechanical properties. The sheets are then annealed at a temperature between about 1300° F. to about 1550° F. followed by grinding and pickling.

  • Patent number: 8303379
    Abstract: Techniques for manufacturing sheet product of varying surface profile and products thus manufactured are disclosed herein. In some embodiments, the disclosed invention provides a method for profiling a surface of a sheet product having a first profile on first surface. In one embodiment, the method includes creating a profiling template or contoured support surface. A profiled surface may be formed by arranging the profiling template and the sheet product such that the profiling template is located between the sheet product and a support surface, conforming the arrangement of the sheet product and the profiling template to the support surface such that conformance causes the sheet product to have a second surface profile on the first surface, and processing the sheet product to form a third surface profile on the first surface.

  • Patent number: 8229696
    Abstract: According to one embodiment of the invention, a method for preventing the failure of a system, which includes one or more pipes, or one or more cooling jackets, or one or more fluid cooled system components carrying a fluid, involves detecting one or more pressure levels of the fluid in the one or more pipes at one or more points, then comparing the detected pressure levels to a corresponding one or more predetermined limitation values. If the detected pressure levels exceed the corresponding limitation values, a shut-down signal is generated. The shut-down signal triggers the adjusting of one or more systems responsible for causing thermal variations of the fluid, preventing the system from failing while allowing the system to continue operation shortly thereafter.
